在互联网公司，Nginx可以说是标配组件，但是主要场景还是负载均衡、反向代理、代理缓存、限流等场景；而把Nginx作为一个Web容器使用的还不是那么广泛。目前Nginx最新版是1.13，最新稳定版是1.12，它具备大家公认的高性能，而Nginx开发主要是以C/C++模块的形式进行，整体学习和开发成本偏高；因此，nginxScript应运而生：可以在Nginx中使用JavaScript进行动态配置一些变量和动态脚本执行；而目前市面上用的非常成熟的扩展是将Lua和Nginx粘合的ngx_lua模块，并且将Nginx核心、LuaJIT、ngx_lua模块、许多有用的Lua库和常用的第三方Nginx模块组合在一起成为OpenResty，这样开发人员就可以安装OpenResty，使用Lua编写脚本，然后部署到Nginx Web容器中运行。从而非常轻松就能开发出高性能的Web服务。
